DOI: 10.1016/j.commatsci.2019.109410
Abstract: Abstract An “effective bond model” of covalent cross-links between carbon nanotubes (CNTs) is developed for mesoscopic simulations of CNT materials. The cross-links are represented by discrete stretchable bonds between mesoscopic nanotube elements. These bonds induce… read more here.
